I am looking for a small circuit (without using any IC's) to delay the turn off of a 5v logic output for an adjustable amount of time.

At the moment, my project will trigger the turn on (+5v) to a flip flop but it turns off too quickly!
I need to hold the delay the turn off, after the trigger stops for an adjustable amount of time (max 10s) while maintaining the 5V to the output.

Has anybody got a circuit that will do this using discrete components? I don't want to add any more IC's.
